Transition from Childhood to Adulthood in Patients with Duchenne Muscular Dystrophy.

Recently, progress has been observed in the knowledge about Duchenne Muscular Dystrophy (DMD), which is a severe and commonly diagnosed genetic myopathy in childhood, historically resulting in early death. Currently, there are a lot of methods available to improve the clinical course of DMD and extend patients' life expectancy to more than 30 years of age. The key issue for DMD patients is the period between 16-18 years of age, which is described as a transition from pediatric- to adult-oriented healthcare. Adolescents and adults with DMD have highly complex healthcare needs associated with long-term steroid usage, orthopedic, ventilation, cardiac, and gastrointestinal problems. The current paper provides a comprehensive overview of special healthcare needs related to the transfer of a patient with DMD from child-oriented to adult-oriented care. Additionally, the need to organize effective care for adults with DMD is presented.

Challenges of caring for a patient with a rare disease--as demonstrated by Cornelia de Lange Syndrome.

There are over 12,500 diseases defined by European researchers as rare disorders occurring in less than 1:2000 live births. The majority of these manifest in childhood. The clinical picture of a rare disorder is dominated by intellectual disability of various severity and organ defects. Targeted therapy is not available for the majority of rare disorders, therefore multidisciplinary patient care is the only means of improving the quality and duration of the patient's life. In this paper, the authors share their experience organizing a system of care for patients with Cornelia de Lange Syndrome. Over the last 13 years, multidisciplinary diagnostics and consultations were provided to 92 patients and their families, including rehabilitation and psychological support. The model suggested here demonstrates a shorter diagnostic process, continuous contact with the patient, his/her family and pediatrician. Guidelines and recommendations regarding the particular rare disease should be published.

Timed rolling and rising tests in Duchenne muscular dystrophy ambulant boys: a feasibility study.

BACKGROUND: Functional activities are extensively used in motor assessments of patients with Duchenne muscular dystrophy. The role of timed items has been reported as an early prognostic factor for disease progression. However, there are two functional activities that are not widely assessed in clinical practice among Duchenne muscular dystrophy patients: rolling and bed rising. This study aimed to investigate whether the 360-degree roll (roll) and supine to sit-to-edge (bed rise) measurements are feasible tools reflecting the functional status of ambulatory DMD children by establishing possible correlations between validated measures: the Vignos Scale (VS), timed rise from floor and the 6-Minute Walk Test (6MWT). METHODS: A total of 32 ambulant boys with DMD were assessed using timed items, the 6MWT and VS. RESULTS: The roll and bed rise are correlated with each other. The 6MWT, the floor rise and VS are correlated with the roll and with the bed rise. CONCLUSIONS: Findings offer preliminary empirical evidence addressing feasibility and safety of roll and bed rise measurements. There is a potential clinical utility of these tests in assessing functional status of DMD ambulant patients.

The Association between the Respiratory System and Upper Limb Strength in Males with Duchenne Muscular Dystrophy: A New Field for Intervention?

Progressive, irreversible muscle weakness is the leading symptom of Duchenne muscular dystrophy (DMD), often resulting in death from respiratory muscle failure. Little is known about the relationship between the functioning of the respiratory system and the hand grip-a function which remains long preserved. This study aimed to investigate the interdependence between muscle strength and the function of both hand grip and the respiratory system in patients with DMD. MATERIALS AND METHOD: The study included cohort patients, aged 6-17, with DMD, recruited from the Rare Disease Centre, Gdansk, Poland. Clinical status (Vignos scale, Brook scale), pulmonary function (respiratory muscle strength-MIP, MEP); spirometry (FEV1; FVC), as well as upper limb function (performance of the upper limb-PUL 2.0) and hand grip strength (HGS) (hand-held dynamometer) were evaluated in all participants. RESULTS: Finally, 53 boys (mean age 11.41 ± 3.70 years, 25 non-ambulant) were included. Each of the participants presented a lower %pv of MIP (48.11 ± 27), MEP (38.11 ± 22), PUL (75.64 ± 27), and HGS (33.28 ± 18). There were differences between the ambulatory and non-ambulatory groups in values of MIP, MEP, FVC, PUL, HGS (p < 0.001 for all), and FEV1 (p < 0.013). There were correlations between PUL, HGS, and MIP (R = 0.56; R = 0.61, p < 0.001 both), MEP (R = 0.59; R = 0.62, p < 0.001), FVC (R = 0.77; R = 0.77, p < 0.001), and FEV1 (R = 0.77; R = 0.79; p < 0.001). These correlations were found for all participants, but non-ambulatory patients presented stronger relationships. CONCLUSIONS: 1. The pulmonary and upper limb functions were within the normal range in ambulatory and low in non-ambulatory patients with DMD, but the muscle strength of both systems was low, regardless of the stage of the disease. 2. There seems to be an interdependence between the respiratory system and upper limb strength in terms of muscle strength and function in DMD patients, which is stronger in non-ambulatory patients. This may be the basis for the creation of a new personalized plan in rehabilitation-the simultaneous rehabilitation of the respiratory and upper limb muscles. Further studies on this theory should be conducted.

Respiratory Telerehabilitation of Boys and Young Men with Duchenne Muscular Dystrophy in the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic forced reorganization of the multidisciplinary healthcare system for Duchenne muscular dystrophy. Digital solutions seem to be optimal for providing rehabilitation at this time. The aim of this study was to investigate whether it is possible to conduct respiratory physical therapy with the use of telerehabilitation in Duchenne muscular dystrophy. METHODS: The study was conducted during an online conference for families with DMD. During the physical therapy panel we showed the video with the instructions of respiratory exercises. All participants (n = 152) were asked to fill in the online survey evaluating the quality, acceptance, and understanding of the instructions. RESULTS: The survey was filled in by 45 (29.6%) participants. The mean rating of satisfaction was 4.70/5, and for intelligibility was 4.78/5. Thirty-seven (82.2%) patients declared that they had performed the exercises, all caregivers declared that it was possible to perform the proposed exercises a few times a week or daily, and only two respondents replied to invitations to individual online sessions. CONCLUSIONS: Findings from the study show that respiratory telerehabilitation may be implemented for DMD patients; however, the interest in digital rehabilitation among caregivers of DMD boys in Poland is low. The reasons for this situation require further research.

Establishing a telerehabilitation program for patients with Duchenne muscular dystrophy in the COVID-19 pandemic.

BACKGROUND: Duchenne muscular dystrophy is a genetic disease characterized by gradual loss of motor function, respiratory failure and cardiomyopathy. During the time of the global coronavirus pandemic, maintenance of social distancing and self-isolation might complicate regular multidisciplinary care of patients with Duchenne muscular dystrophy but on the other hand may lead to new medical care telehealth solutions. The aim of the study was to investigate patients' situation regarding rehabilitation in the pandemic, to establish an online rehabilitation program and motor assessment and to determine the needs of telerehabilitation in this group. METHODS: The project involved 69 boys with Duchenne muscular dystrophy. The rehabilitation program was presented during online workshops for patients and caregivers. The same program was recorded on video and published in the internet. The online motor assessment tool consisted of six motor tests, caregivers were asked to perform the tasks and share a photograph of the patient's posture using a designed app. RESULTS: In the nonambulant group the emphasis was placed on chest physiotherapy, stretching of upper extremities, positioning and wheelchair ergonomics. The program for the ambulant group focused on lower extremities stretching and full body exercises. Response rate for the workshops for ambulant patients was 29.7%, and only 9.0% for nonambulant patients. Videos showing exercises were displayed 132 times within a month. CONCLUSION: With the physiotherapist guidance (online communication or video) patients with caregivers' help can continue home based rehabilitation. Online videos/instructions/video guidelines are more acceptable by parents/caregivers of patients with Duchenne muscular dystrophy than live workshops.
